BPG 8506


BPG 8506 is a sheet made of expanded graphite reinforced by a flat stainless steel foil (316L – thickness 0.05 mm) which facilitates its handling properties.



Due to its high compressibility and good resistance to creep makes BPG 8506 suitable for demanding conditions in the petro-chemical, - process, - chemical, - power plant industries, especially for pumps, valves, compressors and flange connections.
